Password Security PAP and CHAP support (RFC 1334 plus major vendor variations) if required in login script. Computers Hidden By NAT Network address translation (NAT) opens a temporary path to the Internet for requests originating from the local network. [. . . ] You can update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc. ). You can also access your FTP server or Web site on your own computer using a DNS-like address (e. g. myhost. dhs. org, where myhost is a name of your choice) which will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address. First of all, you need to have registered a dynamic DNS account with www. dyndns. org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a DNS name. The Broadband Router+Firewall, at the time of writing, supports the www. dyndns. org client. You can apply to this client for Dynamic DNS service. 6. 1. 1 DYNDNS Wildcard Enabling the wildcard feature for your host causes *. yourhost. dyndns. org to be aliased to the same IP address as yourhost. dyndns. org. This feature is useful if you want to be able to use for example www. yourhost. dyndns. org and still reach your hostname. The table following the figure describes the fields contained within.

Requested services are identified by port numbers in an incoming IP packet. For example, a packet that is sent to the external IP address of your router and destined for port number 80 is an HTTP (Web server) request, and port 21 is an FTP request. [. . . ] After the modem goes through its self-test, check to see if you now have an IP address. Ensure that your cable or DSL modem is DHCP-capable. You may have to enter the router or host name in the Setup page of the Broadband Router+Firewall's web configurator. Go to the Basic -> Setup section of the web configurator for more information.
